CIRCULAR-SAW MILL.

SPECIFICATION forming part of Letters Patent No. 252,689, dated January 24, 1882.

Application filed September 5, 1881. (No model.) I

To all whom 'it may concern:

Be it known that I, CHARLES J. L. MEYER, of Fond du Lac, \Visconsin, have invented a new and useful Saw-Mill for Small Timber, of which-the following is a specification.

My invention relates to improvements in machines tor handling and cutting small logsoor timber into railway ties, saw-cants, and like pieces; and the objects of my improt'ements are, first, to provide a continuous feed to and between parallel saws adapted to cut slabs simultaneously from each side of the log; second, to centerthe log automatically, and, third, to secure or dog the small log upon its narrow carriage. I attain these objects by the mechanism illustrated in-the accompanying drawings, in which Figure 1 is a vertical section of the whole machine. Fig. 2 is a transverse sectional view of the machine. Fig. 3 gives outline views of detached parts.

Upon a suitable t mber frame are mounted the parallel saws w a", and the other appurtenances of the mill described as follows:

The log-carriage consists of an endless chain, A, traveling along the upper side of the frame on ways A A toward and between the saws w 00, and is moved by drums fl} 3 at either end of the frame. This chain is provided with vertical sharp lugs a a, distributed in pairs upon the links at such spaces apart as may be desired, and which serve as head blocks and dogs for the log.

Four or more vertical standards, B B, otuniform length,size, and shape, and parallel with and opposite each other, move through slides 11 I), attached to the outer shearsof the frame, in front of the saws, and are raised and lowered conjoiutly by means of bell-cranks, links,and lever, as shown, or by other equivalent mechanism. The heads ot'these standards are uniforrnly flared outwardly and beveled on their inner t'aces,.so as to form together the wyes B B. These standards being uniform and equidistant from the chain-carriage A, i-tis obvious that the log rolled into the w es B B must rest with its axis perpendicular to and parallel with the center line ot' the chain-carriage; in other words, it must center itself.

, row that a further dog device is requisite. Tns

dog is supplied byaheavy wheel provided with spikes in its periphery (J. This spiked wheel is suspended over the center of and its axis is at right angles with the chain-carriage A, and plays up and down in that position by means of the frame, slideways, pulleys, cord, and balance-weight e d e f, as shown, or other equivalentdevice. This spiked wheelt-ngages and dogs the log as it reaches the saws new, and as it passes between and is cut by the saws the wheel revolves upon and with its weight and spikes holds it firmly to its place.

I claim as my invention and desire to secure by Letters Patent- 7 I 1. In a saw-mill t'n stabbing ties and small timber, the adjustable b.d or '\v \es B B, in combination with the log-carriage and saws, substantially as-and for the purposes shown and described.

2. The Ct)l'l]l)ltlttllt)ll,lll a mill for-cutting ties or small cants, ot' parallelsaws 41 .r, chain-carriage A A, the adjustable and reciprocating bed or wyes B B, and the wheel-dog 0, substantially as shown.
